The formula I previously posted for the resonant frequency of an "unloaded"
helix can be cast in a slightly different form which is similar to the form
Mark B posted:
c
F = 
4x length of winding
The above formula does not take into account the coiling of the wire.
Written in similar terms to the above, the formula I posted becomes:
c (1/5)
F =  x (5/4) x (H/D)
4 x length of winding
c=speed of light
H=height of coil
D=diameter of coil
Nothing special. Just highlights the difference due to coiling the wire.
For an H/D=10, the two forms differ only by a factor of 2.
SOrry to beat a dead horse.
